LED Backlight Strip Set
Individual LED diodes in the backlight array have reached the end of their service life or failed due to thermal stress. Replacing the entire set of strips ensures uniform luminosity and color temperature across the panel. This directly addresses the 'dark spots' caused by dead zones in the grid.

Power Supply Board
The power supply board contains the LED driver circuitry responsible for regulating current to the backlight zones. A component failure in the driver stage (such as a capacitor or MOSFET) can lead to insufficient voltage for specific LED strings, causing them to appear faded or completely dark.

T-Con Board
While primarily responsible for image processing and timing, the T-Con board communicates with the backlight array for local dimming functions. A logic error here could theoretically cause improper zone illumination, though it is much less likely than physical LED failure.
